Application filed March 6, 1914. Serial No. 822,920.

To all whom it may concern:

Be it known that I, FREDERICK ARTHUR ELLIS, a subject of the King of Great Britain, residing in London, England, and whose post-office address is 19 Tregothnan road, Clapham, in the county of London, England, have invented certain new and useful Improvements in Detachable Vehiclefication.

This invention relates to detachable wheels for vehicles of the kind in which the. detachable part, usually comprising hub, spokes and felly or the equivalent thereof, is carried by a plurality of driving pins or studs projecting outwardly from a permanent or non-detachable hub disk and passing through holes in the hub of the detachable wheel, which is locked against axial displacement by means of a locking ring having a number of slots so formed as to permit the ring to be passed over the ends of the driving pins and then rotated so as to engage under heads or collars, or equivalent projections, formed upon the ends of the pins, means being provided to prevent the circumferential displacement of the locking ring, as for example by one or more spring-urged pins.

The present invention comprises a wheel of this type wherein the rotation of the locking ring is prevented positively, without dependence upon an axle cap, by means of one or more locking pins accommodated within the detachablehub and removable therewith which, when the detachable wheel and locking ring are assembled, are projected either automatically by means of springs or by the application of a suitable tool, into locking engagement with the ring.

' The invention further comprises a wheel of this kind wherein means are provided for sin'iultaneously actuating two or more locking pins, and further a wheel of this kind wherein the locking pin or pins are arranged to project into the slot or' sl0ts in the locking ring in which the driving pins engage so as to provide an abutment for the latter.

These and other novel features will be described more specifically with reference to the accompanying drawings, wherein- Figure 1 is an end elevation of the hub of a detachable wheel embodying this invention; Fig. 1 shows part elevation of a modification of the hub of Fig. 1 with the locklooking ring for use with the hub shown in Fig. '71:; Fig. 7 similar views of another ring forming part of the locking device of the construction shown in Figs. 4 and 5; Fig. 8 another part of the same device, and Fig. 9 is a section illustrating an auxiliary lock-' ing device.

Referring first to Figs. 1 and 2 a repre-' sents thehub of a detachable wheel which may be of the artillery wheel type or any other kind of wheel applicable to road we hicles, Z2 represents a permanent hub disk which carries a plurality of pins 0 which are secured to the permanent hub disk and project through holes in the deachable hub a, the ends of the studs projecting beyond the face of this hub and being circumferentially grooved so as to leave collars or heads 0' upon their projecting ends. A locking ring (Z having slots d corresponding in number with the pins 0 and formed -with an enlarge- 1 vb by engagement of the edges of the narrow part of the slots d under the collars or heads 0 of the studs. Circumferential displacement of the locking ring d is prevented in the construction of Figs. 1 and 2 by a spring-urged pin or plunger 6 which is accommodated in an axially alined recess 6 in the hub a and is retained therein by suitable means such as the plate 6 screwed over the end of the recess, which plate is formed with a hole to allow the plunger 6 to project through it while acting as an abutment to a collar on the plunger when the latter is urged outward by the spring 6 j \Vhen the locking ring (1 is rotated into the position shown in Figs. 1 and 2, the plunger 6 comes into register with a hole 6 in the locking ring and under the action of the spring 6 is projected through the hole, thereby locking the ring dagainst circumferential movement. Ihe plunger 6 is preferably slightly tapered, as is also the hole 6 in the locking ring in which it engages so as to take up any slight wear there may be. Further, the locking ring (2! may have one or more circumferential grooves 03 on its under face to accommodate a spring ring or rings adapted to take up any looseness due to wear between the locking ring and the wheel hub.

To remove the wheel a suitable tool is provided for depressing the plunger ,6 clear of a.

the locking ring 05, and preferably an undercut recess 03 is formed in the locking ring 03 as a fulcrum for the nose of this tool. Instead of a single spring bolt 6, two or more may be provided, the tool for depressing them being modified accordingly. Further, the spring bolt or bolts may be arranged in the detachable hub to project into and fill the clearance space of the slots d. in the locking ring when the latter is assembled in the locked position as shown in Fig. 1*.

In lieu of the spring bolts or plungers 6 one or more screwthreaded pins orbolts such as f (Fig. 3) may be substituted, the outer end of such bolts being formed with a square hole f or equivalent device for the application of a tool which is inserted through the corresponding hole in the locking ring d when the latter is in the operative position and the said hole or holes register with the screwthreaded pins, so as to enable the pins 7 to be screwed outwardly untilflush with the locking ring d, thereby holding the latter against circumferential displacement. Y

The locking pins f, when more than one are used, may be independently screwed into the locking position, or any suitable device may be adopted for operating the pins simultaneously. As in the case of the spring pins 6, the screwthrcaded pins f may be arranged to occupy the clearancespace in the slots at of the locking ring whenthe latter is in the locking position.

In the modified construction of Figs. 4, 5, 7 and 8 the pins 9 which secure the locking ring 0? against circumferential displacement are carried upon and project outwardly from a ring it which is axially movable by the operationof sleeves i the lower ends of which are beveled or cam-shaped and rest upon correspondingly shaped cam studs or sleeves 9'. Within the sleeves i, j and stepped in the permanent hub plate I) are studs the outer ends of which have a bearing in arc-shaped slots 03 in thelocking plate d and have square recesses in their ends whereby they may be rotated by means of a suitable key. Projecting outwardly from each of these studs in is a pin is which engages a vertical slot z'QfOrmed in each of the sleeves i, so that when the studs 70 are rotated about their. axis the sleeves 2' turn with them and,

riding upon the cams j, force the plate It outwardly so as to project the heads of the locking'pins 9 into holes or recesses in the 4 locking ring d, for example the clearance space left in the slots 05 when the locking ring is turned to the operative position.- The actuation of one of the studs la by means of a suitable tool causes the other sleeves i, besides the one associated with the particular stud which is being actuated, to rise upon their cams j by reason of the fact that each of the sleeves i has a crank 21 which is connected by a link i with a ring or plate m situated below the cams j and slotted, as shown atm, to allow rotation of the,ring

within the necessary limits. This rotation ing ring d.

Rotation of the cam sleeves j is prevented by providing them with a tooth j which projects downwardly into the slot m of the ring m, as shown in Figs. 5 and 5 The driving pins 0 are not shown in Figs. 3 to' 8, but it will be understood that they project from the fixed hub plate 6 through the holes 1n the several parts marked 0, while the pins 9 pass through the holes in the several parts marked 9, and the actuating pins is pass through "the, holes in the ring it marked 70. j

The device shown in section in Fig. 9 for preventing accidental circumferential move-f ment of the locking ring d may be used as an alternative or in addition to, the locking pin or pins previously described. When used in addition to such locking pin or pins it operates to prevent a releasing movement of the locking plate d when the latter has been turned through an insufficient angle to permit the locking pin or pins 'to be projected into the aperture or aperturesv in the locking ring with which they cooperate. As shown, the device consists of a circumferential or arc-shaped ratchet 0 formed upon or attached to the face of the spring which is accommodated in a recess or cavity formed on the inner side of the locking ring d, and the head of the pawl p is preferably provided with an eyepiece p whereby the pawl may be retracted when it is desired to rotate the locking ring into the unlocking position.

The disposition of the ratchet and pawl is such that they become operative as soon as the locking ring is turned out of the locking invention and the best means I know of carrying the same into practical effect I claim 1. A detachable Wheel for road and other vehicles, comprising a fixed hub, a removable hub having a series of axially alined holes and also a separate axially alined recess, a locking ring having a number of holes, driving pinssecured to the fixed hub and passing through the holes in the removable hub and locking ring, and a locking member accommodated in the said recess and adapted to engage the locking ring when the latter has been given a partial turn and thereby prevent accidental circumferential displacement of the same.

2. A detachable wheel for road and other vehicles, comprising a fixedhub, a removable hub having a series of axially alined holes and also a separate series of axially alined recesses, .a locking ring having a number of holes, driving pins secured to the fixed hub and passing through the holes in the removable hub and locking ring, a plurality of locking pins arranged in said recesses and adapted to engage in the locking ring,-and means for actuating said locking pins simultaneously.
